Thanks for the feedback – it all goes into making future tutorials better! In the meantime, we welcome submissions from our visitors if you’d like to create or share an alternative version of any of the tutorials. I agree, this tutorial could use a mite more context. It’s always a bit of a balancing act – too much context and some people want you to “get to the point”, too little and others are confused. While we can’t please all the people, all the time, over time it’s great to see which things work and don’t for our users.
